Objective: To explore the effects that impaired ability to sit-to-stand has on upright mobility and self-care in children with cerebral palsy and how this in turn may affect their caregivers., Methods: A mixed methods research design was conducted with 25 children who had cerebral palsy with moderate to high mobility limitations (GMFCS levels III and IV) and their caregivers. Caregivers were interviewed about their child's mobility and self-care. The independence of each child's activities was rated using the mobility and self-care domains of the Functional Independence Measure for Children (WeeFIM)., Results: Two themes were identified from qualitative analyses: Difficulty in sit-to-stand was perceived by caregivers to reduce their child's ability to independently and safely perform mobility and some self-care tasks; and negatively impacted the caregivers physically and psychologically. Mobility and self-care WeeFIM scores showed that these children required moderate assistance, and that self-care tasks involving sit-to-stand (toileting and bathing) required more assistance than self-care tasks that would not be expected to involve sit-to-stand (eating and grooming). Qualitative and quantitative findings were convergent., Conclusions: The ability to sit-to-stand independently may be an important precursor skill for independence in upright mobility and self-care for children with moderate to severe mobility limitations.

Aims: To explore caregiver perceptions about the outcomes and feasibility of a high repetition sit-to-stand home-based exercise program on themselves and their children with cerebral palsy who have mobility limitations., Methods: Face-to-face semi-structured interviews were conducted with 19 caregivers (17 women, mean age 39 y 6 mo (SD 8 y 4 mo) of 19 children with cerebral palsy (10 males, mean age 7 y 2 mo (SD 2 y 1 mo) classified as level III (n = 8) or IV (n = 11) on the Gross Motor Function Classification System. The children had completed a 6-week task-specific sit-to-stand exercise program. Each week a physical therapist and caregivers supervised the program: twice by the physical therapist and three times by the caregivers. Interviews were completed immediately after program completion, and transcripts were analyzed using a process of inductive thematic analysis within an interpretive description framework., Results: Themes were: (1) caregivers saw positive changes in their children from completing the program, (2) seeing positive changes gave caregivers hope that their child could develop with further training, and (3) the program was feasible to complete., Conclusions: Caregivers perceived positive changes in their children and expressed increased hope for their child's future after a high repetition sit-to-stand exercise program, suggesting the program is feasible with caregiver supervision.

Aim: To investigate if a sit-to-stand exercise programme for children with cerebral palsy (CP) would improve self-care and mobility., Method: Thirty-eight children with CP (19 males, 19 females; mean age 8y 0mo, SD 2y 4mo, age range 4y 0mo-12y 4mo) classified in Gross Motor Function Classification System (GMFCS) levels III and IV and their caregivers were randomly allocated to sit-to-stand training plus routine physiotherapy (balance and gait training) or routine physiotherapy only (controls). Task-specific sit-to-stand training was completed five times a week for 6 weeks under physiotherapist (twice weekly) and caregiver (three times weekly) supervision. Blinded outcome assessments at week 7 were the self-care and mobility domains of the Functional Independence Measure for Children, Five Times Sit-to-Stand Test (FTSST), and Modified Caregiver Strain Index (MCSI)., Results: The sit-to-stand group self-care increased by 2.2 units (95% confidence interval [CI] 1.3-3.1) and mobility increased by 2.2 units (95% CI 1.4-3.0) compared to the control group. In the sit-to-stand group, the FTSST was reduced by 4.0 seconds (95% CI -4.7 to -3.2) and the MCSI was reduced by 0.8 units (95% CI -1.2 to -0.4) compared to the control group., Interpretation: A sit-to-stand exercise programme for children with CP classified in GMFCS levels III and IV improved sit-to-stand performance and resulted in small improvements in self-care and mobility, while reducing caregiver strain. What this paper adds Sit-to-stand training improved independence in self-care and mobility for children with cerebral palsy (CP). Home-based sit-to-stand training programmes for children with CP can reduce the burden on supervising caregivers., (© 2021 Mac Keith Press.)

Aim: To explore the barriers to and facilitators of physical activity for young people with cerebral palsy in specialist schools., Method: Eleven focus groups involving 73 participants (10 young people with cerebral palsy, 13 parents of children with cerebral palsy, 27 teachers, 23 therapists) were held at two specialist schools. Focus groups were audio-recorded and transcribed verbatim. Transcripts were analysed using inductive thematic analysis by two researchers, independently., Results: Four main themes emerged from the focus groups: school priorities; student factors; staffing and environment; and roles and relationships. Physical activity was promoted when academic work and physical activity were seen as equally important school priorities. Student factors that reduced physical activity included fluctuating health, school absences, and protracted rehabilitation after surgery. The staffing and environment unique to specialist schools played a pivotal role in assisting students to be active, as was the importance of collaborative, relationship-based care., Interpretation: Physical activity programmes developed in specialist schools need to take into consideration complexities associated with the age, developmental stage, and academic requirements of young people with cerebral palsy. Particularly for adolescents, motivation was discussed as having a substantial influence on physical activity participation. These findings may assist school leadership teams, clinicians, and teachers in planning physical activity interventions., What This Paper Adds: Specialist schools offer custom-built environments that promote physical activity and inclusion for students with physical impairments. Therapists and teaching staff work creatively and collaboratively to incorporate an 'all-day' approach to providing physical activity opportunities. Balancing time spent on physical activity versus academic work can cause tension., (© 2019 Mac Keith Press.)

Purpose: To evaluate the safety, adherence, and estimates of effect of an aerobic exercise program in specialist schools for young people with cerebral palsy., Methods: Nineteen students with cerebral palsy were randomly allocated to an intervention group who completed an aerobic exercise program (27 sessions over nine weeks) or a control group who completed social/art activities over the same time., Results: There were no serious adverse events and the exercise program was completed with high rates of attendance (77%) and adherence to target heart rate zones (79%). Effect sizes favored the intervention group for measures of cardiovascular performance (sub-maximal treadmill test, effect size d = 0.7; muscle power sprint test, d = 0.9) and participation (Preference for Active-Physical Activities, d = 0.6)., Conclusions: An aerobic exercise program in specialist schools for young people with cerebral palsy, that may improve measures of cardiovascular performance, can be completed safely, with moderately high levels of adherence.

Purpose: To explore the perceived effects of an aerobic exercise program delivered in specialist schools for young people with cerebral palsy with high support needs., Methods: In-depth interviews were completed with 8 students with cerebral palsy, 10 parents, 8 teachers and 7 physiotherapists. Interviews were audio-recorded, transcribed verbatim and independently coded by two researchers. Data were analyzed using thematic analysis., Results: Two themes emerged: one about program impact and the second about influential design features. Exercise was perceived as important, and participants indicated that the program had resulted in positive physical (e.g., improved ease of mobility, fitness and stamina) and psychosocial (e.g., happiness, social experience, challenge) impacts. The school setting, program staff and student attitudes were key features of the program., Conclusions: These data converge with those from a randomized controlled trial and attribute physical and psychosocial benefits to a specialist school-based exercise program for young people with cerebral palsy.

Purpose: To examine if individualised resistance training increases the daily physical activity of adolescents and young adults with bilateral spastic cerebral palsy (CP)., Method: Young people with bilateral spastic CP were randomly assigned to intervention or to usual care. The intervention group completed an individualised lower limb progressive resistance training programme twice a week for 12 weeks in community gymnasiums. The primary outcome was daily physical activity (number of steps, and time sitting and lying). Secondary outcomes included muscle strength measured with a one-repetition maximum (1RM) leg press and reverse leg press. Outcomes were measured at baseline, 12 weeks and 24 weeks., Results: From the 36 participants with complete data at 12 weeks, there were no between-group differences for any measure of daily physical activity. There was a likely increase in leg press strength in favour of the intervention group (mean difference 11.8 kg; 95% CI -1.4 to 25.0). No significant adverse events occurred during training., Conclusions: A short-term resistance training programme that may increase leg muscle strength was not effective in increasing daily physical activity. Other strategies are needed to address the low-daily physical activity levels of young people with bilateral spastic CP., Implications for Rehabilitation: Progressive resistance training may increase muscle strength but does not lead to increases in daily physical activity of young people with bilateral spastic cerebral palsy (CP) and mild to moderate walking disabilities. Other strategies apart from or in addition to resistance training are needed to address the low daily physical activity levels of young people with bilateral spastic CP and mild to moderate walking disabilities.

Aim: The aim of the study was to describe daily physical activity levels of adolescents and young adults with bilateral spastic cerebral palsy (CP) and to identify factors that help predict these levels., Method: Daily physical activity was measured using an accelerometer-based activity monitor in 45 young people with bilateral spastic CP (23 males, 22 females; mean age 18y 6mo [SD 2y 5mo] range 16y 1mo-20y 11mo); classified as Gross Motor Function Classification System (GMFCS) level II or III and with contractures of <20° at hip and knee. Predictor variables included demographic characteristics (age, sex, weight) and physical characteristics (gross motor function, lower limb muscle strength, 6min walk distance). Data were analyzed using the information-theoretic approach, using the Akaike information criterion (AIC) and linear regression., Results: Daily activity levels were low compared with published norms. Gross Motor Function Measure Dimension-E (GMFM-E; walking, running, and jumping) was the only common predictor variable in models that best predicted energy expenditure, number of steps, and time spent sitting/lying. GMFM Dimension-D (standing) and bilateral reverse leg press strength contributed to the models that predicted daily physical activity., Interpretation: Adolescents and young adults with bilateral spastic CP and mild to moderate walking disabilities have low levels of daily activity. The GMFM-E was an important predictor of daily physical activity., (© 2014 Mac Keith Press.)

Aim: The aim of this study was to investigate whether individualized resistance training improves the physical mobility of young people with cerebral palsy (CP)., Method: Forty-eight participants with spastic diplegic CP (26 males, 22 females; mean age 18y 1mo, SD 1y 11mo) classified as level II or III on the Gross Motor Function Classification System were allocated randomly to progressive resistance training or usual-care control. Resistance training was completed twice weekly for 12 weeks at a community gymnasium under the supervision of a physiotherapist. Exercises were based on instrumented gait analysis and targeted muscles contributing to walking difficulties. Outcomes at 12 weeks and 24 weeks included objective measures of mobility (6-min walk test, instrumented gait analysis, and Gross Motor Function Measure dimensions D and E), participant-rated measures of mobility (Functional Mobility Scale and Functional Assessment Questionnaire), and muscle performance., Results: The strength of targeted muscles increased by 27% (95% CI 8-46%) compared with control group. There were no between-group differences in any objective measure of mobility at 12 weeks (6-min walk test: mean difference 0.1m; 95% CI -21 to 21m) or at 24 weeks. Participant-rated mobility improved (Functional Mobility Scale at 5m: mean 0.6 units; 95% CI 0.1-1.1 units; Functional Assessment Questionnaire: 0.8 units; 95% CI 0.1-1.6 units) compared with control group at 12 weeks., Interpretation: Individualized progressive resistance training increased strength in adolescents and young adults with spastic diplegic CP. Despite participant-rated benefits, the increased strength did not result in objective improvements in mobility., (© 2013 Mac Keith Press.)

Purpose: To systematically review and compare the daily habitual physical activity levels and sedentary times of young people with cerebral palsy to their typically developing peers and to physical activity guidelines., Method: After searching electronic databases, two reviewers independently applied criteria. Studies were required to include young people with cerebral palsy (up to 18 years) and to quantitatively measure habitual physical activity, defined as activity across at least one day. Data extraction was independently verified, and quality analysis completed by two reviewers., Results: Of 895 identified studies, six moderate to high quality studies were included. There were four measures of habitual physical activity. Participants were aged 5 to 18 years and typically had moderate to high gross motor function. Across all ages and levels of motor function, young people with cerebral palsy participated in 13% to 53% less habitual physical activity than their peers. Levels of activity were approximately 30% lower than guidelines. Sedentary times were twice the maximum recommended amount., Conclusions: Young people with cerebral palsy participate in significantly lower levels of habitual physical activity than their peers, and less than recommended guidelines. Long-term negative health consequences of inactivity such as metabolic dysfunction, cardiovascular disease and poor bone density are therefore more likely.

Background: In young people with spastic diplegic cerebral palsy weakness of the hip extensor muscles are associated with limitations in activity. It is important that clinicians can reliably measure hip extensor muscle strength to monitor changes over time and the effects of any interventions. Previous research has demonstrated high reliability for measuring strength of all muscles of the lower limb, with the exception of the hip extensors. Therefore the aim of this study was to examine the retest reliability of measuring hip extensor strength in young people with cerebral palsy., Methods: Using a test-retest reliability research design, 19 participants with spastic diplegic cerebral palsy (Gross Motor Function Classification System Levels II and III) (mean 19 y 2 mo [S D 2 y 5 mo]) attended two testing sessions held 12 weeks apart. Three trials with a hand-held dynamometer were taken at each testing session in supine, prone and standing. Retest reliability was calculated with Intraclass Correlation Coefficients (ICC(2,1)) and with units of measurement (kilograms) converted to a percentage strength change., Results: ICC values ranged from .74 to .78 in supine, .75 to .80 in prone, and .73 to .75 in standing. To be 95% confident that real change had occurred, an individual's strength would need to increase 55 to 60% in supine, 86 to 102% in prone, and 102 to 105% in standing. To be 95% confident that real change had occurred across groups, strength would need to increase 4 to 8% in supine, 22 to 31% in prone, and 32% to 34% in standing. Higher ICC values were observed when three trials were used for testing., Conclusions: The supine testing position was more reliable than the prone or standing testing positions. It is possible to measure hip extensor strength with sufficient reliability to be able monitor change within groups using the supine position provided three trials are used during testing. However, there is insufficient reliability to monitor changes in hip extensor strength in individuals with cerebral palsy unless they exhibit very large strength increases.

Objective: To determine if habitual physical activity could be increased in people with cerebral palsy., Data Sources: We searched electronic databases until February 2010 using key words related to concepts of cerebral palsy and physical activity. This search was supplemented with citation tracking., Methods: Studies had to include participants with cerebral palsy who have habitual physical activity measured over at least one day after a therapy intervention. Two reviewers independently assessed study quality with the PEDro scale (quantitative studies) and Critical Appraisal Checklist for Qualitative Research (qualitative studies). For quantitative studies standardized mean differences were calculated and meta-analysis conducted. Qualitative data were synthesized thematically., Results: Three randomized controlled trials (96 participants) and two qualitative studies (21 participants) were reviewed. Four studies evaluated exercise programmes, and one study an online educational and support programme. Meta-analysis showed that exercise programmes could increase habitual physical activity (δ = 1.0; 95% confidence interval (CI) 0.28 to 1.72). This result was reinforced by reports of increased daily activity in two qualitative studies. The online programme increased weekly minutes of moderate to vigorous physical activity (d = 0.81; 95% CI 0.17 to 1.45), and weekly step counts (d = 0.62; 95% CI 0.0 to 1.25). Positive effects were not maintained after programmes stopped. There was insufficient evidence to determine if demographic factors or programme characteristics, such as intensity and setting, were associated with outcomes., Conclusion: Preliminary evidence suggests that exercise programmes and online support programmes can increase habitual physical activity in people with cerebral palsy, but effects are not maintained when programmes stop.

Objective: To evaluate the efficacy of 9 weeks of twice-weekly partial body weight-supported treadmill training (PBWSTT) for children with cerebral palsy (CP) and moderate to severe walking difficulty compared with overground walking., Design: Randomized controlled trial., Setting: Metropolitan Specialist School for children with moderate to severe physical and/or intellectual disabilities., Participants: Thirty-four children classified level III or IV by the Gross Motor Function Classification System were recruited and randomly allocated to experimental or control groups. Of these, 26 (15 girls, 11 boys; mean age 10 y, 10 mo +/- 3 y, 11 mo [range, 5-18 y]) completed training and testing., Interventions: Both groups completed 9 weeks of twice-weekly walking training. The experimental group completed PBWSTT, and the control group completed overground walking practice., Main Outcome Measures: Ten-meter walk test (self-selected walking speed), 10-minute walk (walking endurance), School Function Assessment., Results: The overground walking group showed a trend for an increase in the distance walked over 10 minutes (F=3.004, P=.097). There was no statistically significant difference in self-selected walking speed over 10 meters or in walking function in the school environment as measured by the School Function Assessment., Conclusions: PBWSTT is safe and feasible to implement in a special school setting; however, it may be no more effective than overground walking for improving walking speed and endurance for children with CP. Continued emphasis on progressive reduction of body weight support along with adding concurrent overground walking practice to a treadmill training protocol may increase the intensity of training and assist with carryover of improvements to overground walking. Treadmill training programs that include concurrent overground walking as an additional key feature of the training protocol need to be rigorously evaluated for children with CP., (Copyright 2010 American Congress of Rehabilitation Medicine.

Purpose: The development of efficient and independent walking is an important therapeutic goal for many children with cerebral palsy (CP). Consequently, there has been growing interest in determining the effects of treadmill training programs for these children., Method: A systematic review of the literature was conducted to evaluate the effectiveness of treadmill training for children with CP. Relevant trials were identified by searching electronic databases and by citation tracking., Results: Of 125 papers initially identified, five met the criteria for review. Results showed that treadmill training is safe and feasible for children with CP across a wide range of ages and functional abilities. Children with more severely affected walking ability significantly increased their walking speed (d = 1.48, 95% CI: 0.49-2.40) and gross motor performance (d = 1.5, 95% CI: 0.50-2.50) after training. However, the results also suggested that treadmill speed and length of training sessions might need to be set to specifically match desired intervention goals such as increasing walking speed or endurance., Conclusions: The review suggests that treadmill training is safe and feasible for children with CP and indicates that there may be some positive benefits in walking speed over short distances and in general gross motor skills. The provision of PBWS may be particularly beneficial for children with more severe walking disability (GMFCS III and IV). Further research is necessary before it can be concluded that treadmill training is beneficial for children with CP.

Purpose: To investigate the extent to which selected individual, family and environmental variables were associated with participation of children who have cerebral palsy in activities outside school., Methods: Data were gathered through a population-based survey of 114 children born in 1994 or 1995 in Victoria, Australia. Participation was measured using the Children's Assessment of Participation and Enjoyment. Selected independent variables were classified as related to the child, family or environment. Linear regression analysis was used to identify variables associated with participation in informal (activities that require little planning) and formal (those with structure and leaders) activities., Results: Participation in informal activities tended to be greater in children who preferred informal activities and who had higher manual ability (adjusted R(2) = 36.3%). Girls and those with better gross motor function also tended to participate in more activities. The explanatory power of the regression model for participation in formal activities was limited (adjusted R(2) = 4.2%)., Conclusion: Knowing a child's activity preferences is critical to intervention planning. Being exposed to a range of activities within supportive environments may provide the opportunity to develop preferences, especially in activities where children with cerebral palsy have reduced participation, such as in physical activities.

Purpose: Understanding self concept is important for therapists treating children with cerebral palsy because knowing what children and parents think about perceived competencies and adequacies can be taken into account in determining treatment goals. This study investigated: (i) If differences existed between the self concept ratings of children with cerebral palsy compared to their parent's perception of their child's abilities and attributes, and (ii) the strength of association between the child and parent ratings., Method: Thirty children (14 females, 16 males; mean age 11 years 5 months, SD 2 years 6 months, range 8-16 years) with spastic hemiplegia or diplegia and gross motor skills classified as level I or II on the Gross Motor Function Classification System rated their self-concept using the Self-Perception Profile for Children questionnaire. Their parents completed the accompanying Parent Rating Scale., Results: Group differences between the parents and children were found for the domains of Athletic Competence and Physical Appearance. There was either no relationship or a low level of association between the child and parent ratings in all five domains of self concept assessed., Conclusion: Parents were unable to evaluate their child's self concept accurately suggesting health professionals should gather such information from the child themselves.

This study examined whether the self-concept of children with cerebral palsy (CP) differed from that of children without impairment. Forty-seven children (24 males, 23 females; mean age 11y 8mo [SD 2y 6mo]) with spastic diplegia or hemiplegia were matched with children without impairment. The level of disability of the children with CP was classified as Gross Motor Function Classification System Level I (n=24), Level II (n=16), or Level III (n=7). The 36-item Self-Perception Profile for Children was used to assess six domains of self-concept. No difference was found between the groups for Global Self-worth, Physical Appearance, or Behavioural Conduct. Children with CP scored lower on Scholastic Competence (t(92)=-2.75, p=0.01), Social Acceptance (t(92)=-1.96, p=0.05), and Athletic Competence (t(92)=-3.63, p<0.01) than children without impairment. Males with CP had lower scores for Scholastic Competence (t(46)=-3.54, p<0.01) than males without impairment. Females with CP had lower scores for Social Acceptance (t(44)=-2.31, p=0.03) than females without impairment. Both males and females with CP had lower scores for Athletic Competence than their peers without impairment. These results suggest that children with CP do not have a lower Global Self-worth even though they may feel less competent in certain aspects of their self-concept. Clinicians need to account for this when deciding on management strategies and may need to educate parents, carers, and health professionals that a lower self-concept may not necessarily be associated with a diagnosis of CP.

This matched-pairs, clinical controlled trial evaluated the effects of a school-based, partial body-weight-supported treadmill training (PBWSTT) programme, conducted twice a week for 6 weeks, on the walking speed and endurance of children with cerebral palsy (CP). Pairs of children (10 males, four females; mean age 8 y 10 mo [SD 2 y 6 mo], range 5-14 y) matched for sex, age, type of CP (athetoid quadriplegia, n=6; spastic quadriplegia, n=6; spastic diplegia, n=2), and Gross Motor Function Classification System level (10 at Level I V, four at Level III) were allocated to the experimental or control group. Compared with the control group, the seven treadmill-training participants increased their self-selected walking speed over 10 metres (Mann-Whitney U=9.00, z=-1.98, p=0.048; mean difference 4.21 m/min). A trend was also found for increased distance walked over ground in 10 minutes (t[12]=1.88, p=0.083; mean difference 19.81 m). A relatively short PBWSTT programme can improve the walking speed of children with CP and moderate to severe disabilities. Walking endurance might also improve in some children. Treadmill training seems to be a useful gait training option for children with C P, and it seems feasible to conduct such a programme within a school environment.

This systematic review aimed to determine if differences exist in how a child with cerebral palsy perceives their self-concept and how the child's abilities, behaviors, and attributes are perceived by their parents and teachers. Articles were identified by searching electronic databases. Two reviewers independently assessed the identified articles against predefined inclusion/exclusion criteria. The quality of included articles was assessed against four criteria of methodological rigor. Data were analyzed using effect sizes, meta-analysis, power calculations and independent t-tests. Three articles were included in the review. Meta-analysis indicated that parents of children with cerebral palsy rated their child's abilities and attributes lower than the child's rating (d = 0.66, 95% confidence interval 0.24-1.08). A second meta-analysis did not find a significant difference between the child's and teacher's ratings (d = 0.60, 95% confidence interval -0.44-1.64). These findings suggest that routine assessment of self-concept in children with cerebral palsy by pediatric physical therapists may enlighten the goal setting process of family-centered practice.

Young people with cerebral palsy (CP) are often assumed to have low self-concept, in other words, they do not feel good about themselves. We systematically searched the literature to determine whether this assumption was supported by empirical research. Relevant trials were identified by searching electronic databases, and this was supplemented by citation tracking. Of 1355 papers initially identified, six met the criteria for review. Results showed that adolescent females with CP have a lower self-concept than females without disability in the domains of physical appearance (d = -1.16; 95% confidence interval [CI] -2.06 to -0.26); social acceptance (d = -1.24; 95% CI -2.15 to -0.33); athletic competence (d = -0.93; 95% CI -1.79 to -0.07); and scholastic competence (d = -0.86; 95% CI, -1.71 to -0.01). Adolescent females with CP may be an at-risk group owing to their vulnerable self-concept. Clinicians may need to monitor and implement appropriate intervention strategies with this group. There was insufficient evidence to conclude that children with CP, in general, have a lower global self-concept compared with those without disability.

Purpose: This study examined whether a community-based progressive resistance strength training programme could improve muscle strength and functional activity in a group of adults with cerebral palsy with high support needs., Method: Using a single group pre-post clinical design, 10 adults (7 males, 3 females; mean age 47.8 SD 5.7 years) with cerebral palsy and high support needs completed 4 weeks of introduction and familiarization, followed by a 10-week progressive resistance strength training programme in a community gymnasium. Participants were measured for muscle strength, locomotion speed and timed sit-to-stand., Results: After establishment of a stable baseline from weeks 2 to 5 with no systematic change and a high degree of association (r>0.86), participants increased leg strength by 22.0% (p=0.02), arm strength by 17.2% (p=0.01) and improved performance of sit-to-stand (p=0.02) during the 10-week strength training intervention., Conclusions: This study adds to the accumulating evidence that strength training can be beneficial for people with cerebral palsy by demonstrating benefits for adults with cerebral palsy and high support needs who are subject to decline in physical function associated with the ageing process.

Purpose: To explore the positive and negative perceptions of participating in a strength- training programme for adults with cerebral palsy., Method: Ten adults aged over 40 years with cerebral palsy participated in a group-based 10-week progressive resistance strength-training programme in a community gymnasium. After the programme, each participant was interviewed using an in-depth semi-structured format and the results coded thematically., Results: Participants perceived that their strength, and ability to perform everyday activities had improved. However, the main benefit for participants was enjoyment and social interaction. The only negative perceptions related to fatigue, short-term muscle soreness and a feeling that they had not improved as much as they had expected., Conclusions: Enjoyment, a factor that can promote adherence and sustainability, was a key benefit of this strength-training programme for adults with cerebral palsy that led to perceptions of increased strength and physical functioning. These findings suggest that exercise programmes for adults with cerebral palsy should be conducted in a group in the community, thereby promoting community inclusion. In addition, it is important to provide education to participants about the normal responses and expectations of an exercise programme.

Objective: To evaluate the test-retest reliability of measuring lower-limb strength with a hand-held dynamometer in young people with cerebral palsy (CP)., Design: One rater measured the isometric strength of the lower limbs in 10 participants with CP on 2 occasions separated by 6 weeks., Setting: University movement rehabilitation laboratory in Australia., Participants: Ten young people (mean age +/- standard deviation, 13.5+/-3.4 y) with spastic diplegic CP. Eight of the participants walked independently and 2 walked with assistive devices., Interventions: Not applicable., Main Outcome Measures: Retest reliability of lower-limb strength, expressed in the units of measurement for the interpretation of group mean and individual scores and as intraclass correlation coefficients (ICC(2,1))., Results: For groups, mean lower-limb strength increases of 7 kg (30%) could be interpreted as real change using 95% confidence intervals (CIs). For individuals, for strength gains to be interpreted as real change using 95% CIs, strength increases would need to be greater than 16.8 kg (70%) for the measurement of knee extension and to be greater than 4.3 kg (25%) for ankle plantarflexion. Measurement of hip extension strength was not reliable for group mean or individual scores. All reliability coefficients were greater than.80., Conclusion: A hand-held dynamometer can reliably measure changes in lower-limb strength for groups of young people with CP. It is uncertain whether this method is useful for evaluating change in individuals. Relying only on a coefficient of reliability to decide the usefulness of a measurement can be misleading.

This qualitative study investigated the positive and negative outcomes of a home-based strength-training programme for young people with cerebral palsy (CP). Eleven young people with spastic diplegic CP (seven females, four males; mean age 12 years 9 months, SD 2 years 10 months; range 8 to 18 years) and their parents were interviewed. Gross Motor Function Classification System scores ranged from I (walks without limitations) to III (walks with assistive device), with a mode of III. The strength-training programme, which was conducted in the participants' homes three times per week for 6 weeks (total of 18 prescribed sessions), comprised three exercises targeting the major support muscles of the lower limbs. Exercises were bilateral half squats, heel raises, and step-ups. The training load was increased by adding free weights to a backpack so that 8 to 10 repetitions of each exercise could be performed. Using thematic coding, three categories of outcome emerged: body function and structure, activity, and participation, which were influenced by environmental and personal contextual factors. The programme generated overwhelmingly positive outcomes with only minor negative responses about some equipment and the need for parental involvement. Benefits included perceptions that strength, flexibility, posture, walking, and the ability to negotiate steps had improved. In addition, participants reported psychological benefits such as a feeling of increased well-being and improved participation in school and leisure activities. The contextual factors highlighted the fact that sufficient clinician resources must be allocated to solve individual exercise and equipment problems. As well as providing further evidence that strength training can be beneficial, this study provides useful indicators to guide future quantitative studies of outcomes that are meaningful for people with CP.

This randomized clinical trial evaluated the effects of a home-based, six-week strength-training programme on lower limb strength and physical activity of 21 young people (11 females, 10 males; mean age 13 years 1 month, SD 3 years 1 month; range 8 to 18 years) with spastic diplegic cerebral palsy (CP) with independent ambulation, with or without gait aids; (Gross Motor Function Classification System levels I to III). Compared with the 10 controls, the 11 participants in the strength-training programme increased their lower limb strength (combined ankle plantarflexor and knee extensor strength as measured by a hand-held dynamometer) at 6 weeks (F(1,19)=4.58, p=0.046) and at a follow-up 12 weeks later (F(1,18)=6.25, p=0.041). At 6 weeks, trends were also evident for improved scores in Gross Motor Function Measure dimensions D and E for standing, running and jumping, and faster stair climbing. A relatively short clinically feasible home-based training programme can lead to lasting changes in the strength of key lower-limb muscles that may impact on the daily function of young people with CP.

Objective: To determine whether strength training is beneficial for people with cerebral palsy (CP)., Data Sources: We used electronic databases to find trials conducted from 1966 though 2000; key words used in our search were cerebral palsy combined with exercise, strength, and physical training. We supplemented this search with citation tracking., Study Selection: To be selected for detailed review, reports found in the initial search were assessed by 2 independent reviewers and had to meet the following criteria: (1) population (people with CP), (2) intervention (strength training or a progressive resistance exercise program), and (3) outcomes (changes in strength, activity, or participation). Of 989 articles initially identified, 23 were selected for detailed review., Data Extraction: Empirical studies were rated for methodologic rigor with the PEDro Scale, and studies with a PEDro score of less than 3 were excluded. Review articles were evaluated for quality with the National Health Service Centre for Reviews and Dissemination form., Data Synthesis: Of the 23 selected articles, 11 studies (10 empirical, 1 review) met the criteria for quality and were included. Only 1 randomized controlled trial was identified. With respect to impairment, 8 of the 10 empirical studies reported strength increases as a result of a strength-training program, with effect sizes ranging from d equal to 1.16 (95% confidence interval,.11-2.21) to d equal to 5.27 (95% CI, 4.69-5.05). Two studies reported improvements in activity, and 1 study reported improvement in self-perception. No negative effects, such as reduced range of motion or spasticity, were reported. There was insufficient evidence from which to draw conclusions about the effects of environmental and personal contextual factors., Conclusions: The trials suggest that training can increase strength and may improve motor activity in people with CP without adverse effects. More rigorous studies are needed that have a greater focus on changes in activity and participation and that consider contextual factors., (Copyright 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation)
